Dynamic Spectrum Pricing with Secondary User’s Normal Demand Preference

Abstract

During secondary user's dynamic access to authorized spectrum, a key issue is how to ascertain an appropriate spectrum price so as to maximize primary system's benefit and satisfy secondary user's diverse spectrum demands. In this paper, a scheme of pricing-based dynamic spectrum access is proposed. According to the diverse qualities of idle spectrum, the proposed scheme applies a Hotelling game model to form the spectrum pricing problem. Firstly, establish a model of spectrum leasing, among which the idle spectrum with different qualities constitutes a spectrum pool. en, divide the idle spectrum into equivalent width of leased channels, which will be uniformly sold in order. Secondary users can choose proper channels to purchase in the spectrum pool according to their spectrum usage preferences which are subject to normal distribution and affected by the spectrum quality along with market estimation. is paper analyzes the effect of spectrum pricing according to the primary system's various tendencies to spectrum usage and economic income. Numerical results evaluate the effectiveness of the proposed pricing method in improving the primary system's profits.

“…Because of that, the channel distribution is distributed equally. If a scenario regarding cognitive radio network consists of a particular number of primary and secondary devices, these devices are not equivalent (they are not treated equally) [11][12][13][14][15]. is scenario has a hierarchy, where the primary device has higher access rights to a transfer medium than the secondary device.…”
